IPC: B06B1/10
Filed: 1990-02-05
Abstract: Power pulse generator for machines with pulse action, used for pressing metals, ceramic, metalloceramic and other materials. With the generator, power pulses are generated with high values for power and for the amplitude of the displacement of the pulse body are generated with small external dimensions, a high degree of efficiency, an increased service life and neutralised side forces. The generator consists of a non-moving body to which a box-shaped pulse body is movably connected, moving by means of columns. In the hollow space between them, two identical crank mechanisms are arranged, each of which consists of a lower joint segment, a lower segment arm, an intermediate joint segment, an upper segment arm and an upper joint segment, which are driven from a common crankshaft by means of connecting rods, as a result of which the pulse body is moved backwards and forwards and generates a power pulse. <IMAGE>

Abstract: The period of delay of a delay line (DL), which is formed with a plurality of voltage-control delay elements (D1...D8), is controlled with the aid of a phase-locked loop formed by means of a phase detector (PD) and a low-pass filter (TP), in which a phase comparison between the clock signal supplied to the delay line and the clock signal output by the delay line is carried out and in which a corresponding control voltage is applied to the delay elements; to avoid the phase detector from latching to multiples of the clock period, at least one further output signal of a delay element is additionally evaluated for generating a proportional control voltage.

Abstract: For the transportation of especially semiconductor wafers and for use in processes for the cleaning thereof, a device is proposed in which the wafers are moved by means of fluids, in particular aqueous media. Said device comprises a guide plate (1) in the base (3) of which in each case differently inclined, independent nozzle systems (4, 5, 6, 7) are provided by means of which the transport fluid is forced as required into the transport space, whereby the wafer can be transferred in, braked, rotated and transferred out again. The devices can be combined into treatment lines, in each case different fluids being used in the individual sections. The advantage is that, when braking and rotating, no mechanically moving parts act on the wafers, and that it is not necessary to change chemicals within a treatment station. …<IMAGE>…

IPC: G07F9/00

Abstract: A vending machine antirock mechanism is disclosed which is a safety feature for a soft drink vending maching to prevent rocking of the vending machine. The antirock ratchet mechanism prevents oscillatory rocking of a vending machine by a potential pilferer until a sufficient forward tilt of the machine is attained to possibly allow soft drink products to be pilfered from the machine through the product dispensing chute. A safety problem has been incurred here as the vending machines are very heavy, and can possibly fall on top of and injure the person rocking the machine or other persons in the proximity thereof. The present invention is designed to prevent such rocking motions by mounting an antirock mechanism at one or more locations on the front of the machine, with a vertically movable antirock member therein, such that when the machine is first rocked backwardly, the antirock member moves downward vertically to the floor, and locks in an extended position to prevent the machine from rocking forwardly again. The machine is then jammed in a rearwardly tilted position to prevent oscillatory rocking thereof.

Abstract: In a low-frequency induction heater comprising a primary side coil having a core and a secondary side conductive hollow cylindrical member surrounding the primary side coil, it is sought to improve the Joule heat generation efficiency and solve problems peculiar to composite materials such as thermal deformation, electrolytic corrosion and difficulty of manufacture by forming the conductive hollow cylindrical member using a sole stainless steel material having a thickness ranging from 2 mm to 6 mm. In a preferred embodiment, a coil 2 is wound around a rod-like core 1, which is in turn surrounded by a conductive hollow cylindrical member 3 made of a sole stainless steel material having a thickness ranging from 2 mm to 6 mm. When an AC current passes through the coil 2, an alternating magnetic field is set up in the axial direction of the coil 2, causing an inducted current in the conductive hollow cylindrical member 3. Joule heat is thus generated in the member 3 due to the electric resistance thereof.
